According to this invention thecores, consist ng w dg seed r cy indr e lmots or bundles ofthreads, are obtained through stepwisejad'ding to one or several guidethreads "in a man r which varies according to the design to be pr ducedtlirea'd'swhich are to be used afterwards" either, in workingt'hr'ea'ds or as] guide -threads, or through stegwise sfiparatingsuch threads from a bundle of guide-threads placed any convenient position or direction.

e dg -Shaped "of cyli r a undl Qf knots or threads are either used 'Tllld' pendently or in Connection with flat lace like formations, so that no foreign bodies or oo resare required. The eonsijstence 'ofthe knots or bundles being obtained through the threads worked into thesaine' so that they areadapted to give sufiieient resistance to the fiat lace-like formation or to the hollow forms, into whichthey are worked.

a The invention is'illustrated in the accompanying drawings by ay of example. Figs. '1 to 15 show diagrammatically various forms of execution of the new la'oe-nihkin method! v in order to make the illustrations eas er to understand the thread parts, which are designed to; produce the wedge-form or roller form of the bundle, as well as the fasnin p in s'wh ch old t e hr adhi ls weathe are own as a d ng at ae ta distance apart whilst in reality they] are s ed ea ly weas- Fsrtter th area srar.

shaped or roller-shaped bundles of knots or of threads, are shown as issuing at right angles with regard to the threads which have been added to or separated from the guide-thread" or guide-threads Whilst in reality they issue in any desired direction. The fastening-points are set off through black colouring, the guide-threads and,

guidethread-bundles through hatching.

Figs. l and 2 show two ways of proceeding for the formation 01": wedge shaped and rolle'r shaped bundles of knots or threads. Either the threadends from a bundle Z) of guide-threads, placed accordingto requirement, stepwise one after the other, orthethread-ends f to f are added stepwise one after the other to a guide-thread s placed according to requirement, the bundles of threads thus formed being fastened either at the point r where a thread has been bent off or at the point where a thread has been added. The fastenings 8' are either made with the thread itzhiohj has justbeen'bent off or with the thifad c f s with threads frornthe bundle or with separate fastening-threads 'ac'corcling 'to the aboye rnentioned working methods which eo'nsist in winding, looping, pl aiting twisting, crossing, knotting'or tying respectively. Througl'i the unilateral separation of threadends, according to Fig. 1, and through the unilateral addition of thread- ,ends according to Fig. 2, there are formed in each; case a unilaterally"wedge-shaped bundle of'threads or otknots 7c, the size of which decreases from the head'o towards the point gifth threads are separated from the bundle, or from the point '5 towards the head 0, threads are addedto the bundle.

Whloh issue from the sides of the wedgef to f are bent olf A certain part of the length of the thread is enclosed in the bundle k the ends f to f protruding from the side of the bundle at r or at (2 respectively, the other ends 9 to g of said threads coming out of the headof wedgeshaped bundle, The guide-thread s which remains over when the threads are separated from the bundle or the guide thread which was there before the threads were added issuing with the one end from the head of the wedge-shaped bundle and withftheother end from the point of the same Th idsttreed an's as a Ps 1- H side to a guide-thread a,

t-hread either for the pressing together of all the fastening points of the bundle, or to bring the knotor tlireaddnindle fronrthe wedge-shape into a stretched shape or into any other shape according to the design to be produced.

The stepwise separating or adding of threads from the bundle or to the bundle can be effected at eitherv side of the guide-thread or of the bundle of guide-threads. The addition of: threads at either side of the guide-thread is illustrated in Figs. 3 and A.

Fig. 3 shows how the threads to 7 have simultaneously added at either side of the guide-thread.

Fig. 4t shows how two threadsv to g? are altornatingly added at either side of the guide-thread 2.

Instead of thread-ends, whole threads can be separated "from or added to the bundles as shown in Figs. 5, 6, 7, 8 and 9.

According to Fig. 5 a double wedge-shaped bundle (Z c is formed through adding at first thread-ends f to 7 to a guide-thread z in the manner hereinbe'tore described, and to separate said threads unilaterally as thread-ends g to The base 0 of the part (i of the bundle coincides with the base 0 of the part c, the points i and i of said parts being situated at opposite ends of said bundle.

To form a. bundle 7c of the shape of an equilateral triangle as shown in Fig. 6 the ends f and g of threads are added at either all the thread-ends coming out of the bottom of the triangle, the guide-thread passing through the apex and through the bottom of said triangle; it could however pass only through the apex.

Fig. 7 illustrates the unilateral addition of two thread ends 7 and f/ to one guide thread a, both ends 01"" every thread being simultaneously fastened for a part of its length upon a base. In this manner a unilateral wedge-shaped bundle k is obtained the thread-ends of which come all out of the head 0, the guide-thread 2 coming out at the head and at the point 2'.

As shown in Fig. 8 the unilateral addition of threads bent over at the middle gives a. unilaterally wedge-shaped bundle, the ends 7, g of the threads coming out of the head 0 of the bundle, the guide-thread a coming out at the head 0 and at the point i.

Fig. 9 illustrates by way of example, how through addition of threads at either side of a guide thread a an equilateral bundle is formed, the threads being alternatingly added to the guide thread, their ends f, g hanging out at the head side 0 of the handle.

The stepwise addition or separation of thread-ends can further be executed in such a manner that several guide-threads or bundles of guide-threads are united. Such a form of execution is shown by Way of example in Fig. 10. Through uniting the bundles b to b of guide-threads by plaiting and through equilateral separation of the thread ends 7" to f an equilateral wedgeshaped bundle of threads is formed, in which the thread-ends can serve as guidethreads.

It is obvious that threads which have already been worked into bundles can be further added stepwise to other guide-threads or can be separated again. Fig. 11 shows the addition of thread ends it coming from two different sides to form an equilateral triangular knot, the adjacent end threads of the two bundles serving as guide threads f 7 for the new bundle to be formed, the other threads being added and fastened to the same from either side. The guide-threads could also be formed by independent, separate threads. The etniilateral wedge-shaped bundle which is thus formed is suspended to the thread ends 71.

Fig. 12 illustrates how the unilateral addition of thread-ends k is effected which come from one side, the first of the thread-ends being used as guide-thread. Any of the other thread-ends could however also serve as guide thread. The knot which is formed consists of a unilateral wedge-shaped thread-bundle suspended to the ends of the threads 70.

The threads can further be cut oii stepwise within the wedge-shaped or cylindrical bundle as shown in Figs. 13, 14 and 15.

According to Fig. 13 a cylindrical bundle w of knots or threads of uniform thickness is formed through cutting off stepwise at I the threads a a a which have been added to the guide thread and through simultaneously adding stepwise other threads o 4: 42 which are also cut 0% at t, a new set of threads being added. stepwise and so on. The first new thread o is added so that it is in alignment with and of the first thread a which is parallel with the guidethread, the second new thread 0 so that it is in alignment with the end of the second thread if, the third new thread if being in alignment with and of the third thread u and so on. The circumference m of the cylindrical bundle 'w depends on the number of threads which are added each time.

According to Fig. 14: a unilateral wedgeshaped bundle of threads is formed through the stepwise separation of thread-ends g to g", the ends being then cut off directly behind the point where they are fastened, the ends 25 to t of the threads 9 to g beingthus located in the bundle, the other ends projecting from the head of the bundle.

Fig. 15 shows how an equilateral wedgeshaped bundle is of threads is formed through stepwise separating threads 9 to g from the guide-thread z the threads being cut off at the fastening points If, one end of the ion threads being situated in the bundle, the other end projecting from the head of the bundle.

The stepwise adding or separating of threads to or from a guide-thread or a bundle of guide-threads can be raised according to the design of the lace to be made.

I claim 1. A method for the production of laces and of lace-like products consisting in adding, threads stepwise and successively to a guide thread so that thread bundles are produced, and in fastening the threads of said bundles together by means of one of said added threads.

2. A method for the production of laces and of lace-like products consisting in separating from a bundle of guide threads stepwise, threads designed to serve as working threads, in separating said working threads forming new bundles of said working threads, and in fastening the remaining threads of the bundleof guide threads by means of said working threads.

'1 A method for the production of laces and of lace-like products consisting in separating from a bundle of guide threads stepwise, threads designed to serve as working threads, in separating said working threads forming new bundles of said working threads, and in fastening the remaining threads of the bundle of guide threads by means of separate working threads.

In testimony whereof I aflix my signature in presence of two witnesses.
